come from the oil fields. They are refurbished for use in
non-oilfield rotary applications, such as water wells, HDD, and
construction type drilling. These bits offer significant cost
savings over new bits. Hole Products offers a wide range of
premium, oil field quality re-tip steel tooth bits in sizes ranging
from 2 1/2" to 36". Re-tip bits are available for use in soft,
medium, and hard formations.
